So, what are we looking at here? This shot was reportedly taken on a Chicago Transit Authority train, and while we can’t make out a heck of a lot, we agree with the assessment that this looks like a Motorola model. The phone’s body is lunchboxed, obscured with the help of an nondescript case, but we think we can just discern that Motorola M logo in the upper left that’s often used to hide a tracking ID for these in-development models.

This phone seems to be decently large, but just how big is it? That’s a tough one to narrow down, and the source offers little more than the phone appeared to be at least a five-incher. That makes that 5.2-inch figure start to really resonate, though we’ll need to see more before we can really say with any confidence if we’re looking at the same model. Could this maybe even be the rumored X + 1, due out sometime this summer, or might it be a new model entirely? We can’t wait to find out.
